IMPROVEMEN T IN ALARM-TILLS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom/it mag/ concern: Beit known that I, JOHN F. BALDWIN, ofNashua, in the county of Hillsborough and State of New Hampshire, haveinvented a new and useful Improvement in Alarm-Tills; and I do herebydeclare that the following is a full, clean-and' exact descriptionthereof, which will enable others' skilled .in the `art 4to make and usethe same, reference being had to the accompanying drawings forming partof this specitication.

This invention relates'A to improvements inf alarmtills, and consists inmounting the boltslin' av tilting case, withwhichthe bell-hammer catchis combined fin such away that an effort to withdraw the till `withoutretracting the bolts will cause 'the case to: l

swing back against the bell-l|ammer catch and trip the hammer, to allowit to sound the alarm.

The invention also comprises a novel construction and arrangement of'parts, so as to be cheaply constructed. l

Figure 1 is a scc-tional elevation of my improved till, taken ony thelinea a: of fig. 2.

\ Figure 2 is a section on theline y 'y of `iig. 1.

Figure 3 is atop viewof'a part of th'e till.

' Similar letters, of reference indicate corresponding parts.

` A is 'the drawer Or till.

B, the top, or a section of the table or 4desk into which thetillslides.

C is the hell,

l D, thehammer, and

E, the short arln thereof, which is held by the retaining-catch againstthe action of the springF, which forces` the hammer against the-bell.

When thecatch isdisengaged this spring is conl .nected'to the lng G,attached tothe short arm E, and arranged to strike'against the plate H,when the arm E is let go, to produce th'e necessary springing action`of' the bell-hammer stem` for striking the bell.

The bell-hammer is `p ivoted at I, in ears projecting from the sidefofthe plate H.

'The arrangeme-ntth`us far described does not diier materially `from thecommoiarrangements. l

I proposeto employ 'a spring catching and tripping lever, I, forholdingand tripping the' short arm E of the bell-hammer stem, the samebeingv suitably pivoted at K, or'thereabouts, and provided with anotch,L, and in connection with it I employ a tilting bolt- Vc ase,`M,carrying vertically-moving bolts N, and vso arranged that when 'the tillis pulled forward without l irst causing the bolts to drop, the contactof the latter against the Acatch-plate O will tilt the case back, andcause a projection, P, at one side of the case M, and above thedescendingly-inclined arm of the catolilever L, to bearuponzthelatter,force it down, and

disconnect the bell-hammer.

-The catch I is thrownlup again to catch the arm EV by the spring Q,when pushed back by striking the `stud R, projecting from the top B, atthe time the till is shoved home, and the case is restored by the springR.

shiftingl the curvedv partsN' of the yboltfsfront or rear, they maybe soplaced as to stand in the elevated "position with the upper ends behindthe catch-plate 0,',or be dropped below and pass under it. Thecombinations are `changed by shifting the bolts in this way.

The pivot-bolt T vof the dogs S is also the pivotof the case M, and thedividing-plates V are supported on it. -It is supported at the ends inthe plates H of the outer case.

To facilitate'the removal of the boltsfor changing'v the combinations,lthe side plate-'W is applied in grooves in the end plate X, so as to bedropped in and taken out readily, and this plate Wand the frontsideplate have V-grooves for confining the dividing-v plates V.

Y represents stop projections, toprevent the'case M and the bolts frombeing tilted toO far back.

It will be seen that, by tilting the dogs S backward by the pull-slidesZ and the rods Z', some of the bolts will be thrown up and others down,and by rpulling only those which let the bolts fall, the'till will beunlocked, and these being known to the: authorized person, enables himto openI the drawer readily without striking the bell.

It will also be seen that the case is made wholly, or

nearly so, by casting, and that the dividing-plates and the side plateWare held together 'without the aid offastenings,-other than the grooveswhich are formed in the plates when cast, and which receive the edgesof' the dividing-plates and of the side plate W.

I do'not claim the locking-bolt and three-armed lever as new, but freelyconcede them to `be old and well known to the public.

Having thus described the invention,

I claimias new and desire to secure by Letters Patent- 'l l. Thecombination of the tiltingcase, the-lock ing-bolts, and the bell-catchlever, substantially4 as specified. l

2. lThe locking-bolts N, provided with the curved ends N', and combinedwith the tilting dogs S and a tilting case, M, substantially asspecified.

.3. The case M, provided with the detachable slide W, theIdividing-plates V, and pivoted ou the-rod T,

substantially as specified.
